The LH79520 is a fully-integrated 32-bit MCU based on an ARM720T core. The LH79520 includes a Color LCD Controller and high performance functional blocks that provide a glueless interface to external memory. A fully static design provides low voltage operation and a full compliment of power management features. The LH79520 combines a 32-bit ARM RISC core with a Direct Memory Access Controller, Vectored Interrupt Controller, Color LCD Controller, 32KB of internal SRAM, and several supporting peripherals. The 32-bit ARM720T RISC core provides a powerful instruction set and includes Cache RAM, a Write buffer, Memory-Management Unit (MMU) and Translation Lookaside buffer (TLB). Supporting functional blocks within the LH79520 include Serial and Parallel Interfaces, Counters/Timers, Real Time Clock, Watchdog Timer, Pulse Width Modulators, Infrared support and an on-chip Phase-Lock Loop. JTAG support is provided to simplify debugging.
